If you are running the DxD/Expedition environment, then edit the files:

C:\MentorGraphics\XXXX\SDD_HOME\standard\config\pcb\VBUnits.hkp

C:\MentorGraphics\XXXX\SDD_HOME\standard\config\pcb\VBUnits2002.hkp

Edit the .RESISTANCE_MEASURE section so that the ….DISPLAY “” to ….DISPLAY “ “ or to look like the following. The .SI may have to be replaced with the type of units that you have assigned to your system.

Edit the same files as the resistor valu marking and find the .CAPACITANCE_MEASURE section.

Notice that in my ..SI section that I have left out the ...UNIT "nano" for the ....EXPONENT_VALUE -9. This means the no nano "n" is added to the suffix of the capacitor. Historically a MIL document would only have pico "p" markings on the suffix. So this kind of thing has been done before.
